The solution is to stop using the automatic deployment feature of Tomcat, which takes the shortcut of setting the "context name" (the /myapp part of the URL) to the portion of the WAR filename before ".war".

Instead, extract the WAR contents to the filesystem yourself and setup an XML file at TOMCAT_HOME/conf/[enginename]/[hostname]/[contextname].xml which points the desired context path (such as /myapp) to the location of the application on disk (such as /opt/webapps/myapp-1.1.0/).

The Tomcat reference docs provide a good explanation of how Tomcat deploys applications automatically, and how you can configure customized logic for the mapping of context path to application file location (there are a handful of alternate ways to set this up other than the one I suggest above).
